[Bug libc/3604] New: syslog: messages meant for LOG_KERN go to LOG_USER

["et at tallmaple dot com" <sourceware-bugzilla at sourceware dot org>]

If you call openlog() with LOG_KERN as the facility, it treats this as not
specifying a facility at all, and defaults to LOG_USER.  Thus there is no way to
get anything logged in the 'kern' facility.  The kernel is no exception, as
klogd simply calls openlog() with LOG_KERN like any other userland process.

I observed this on FC4 (glibc 2.3.6-3) but verified it looking at the latest
syslog.c and sys/syslog.h (1.49 and 1.17) in the CVS web access.  LOG_KERN is
defined to be 0, but on line 341 of syslog.c, we ignore any facility of 0 passed
to openlog(), so the default of LOG_USER, assigned on line 70, is kept. 
Similarly, on lines 164-165, we see that a facility of 0 is considered "not
specified".
